Detailed introduction of 1.5 m³ planetary concrete mixer (for concrete pipe production)
1. Principle of planetary concrete mixer
Mixing mechanism: The mixing arm revolves around the central axis while superimposing its own rotation, so that the concrete forms a complex convection motion in the mixing drum, achieving strong shear and high uniformity mixing.

Applicable concrete types: Especially suitable for dry hard concrete (slump ≤ 20mm) and semi-dry hard concrete. This type of concrete is a common raw material for the production of concrete pipes (such as drainage pipes and water pipes), and requires high strength and low air content to ensure the pipe's impermeability and durability.

3. Advantages of CMP1500 planetary concrete mixer in concrete pipe production
 Mixing quality advantages
High uniformity: Planetary motion eliminates mixing dead corners, and the various components of concrete (cement, sand and gravel, admixtures) are evenly distributed, and the strength standard deviation is reduced by 15%-20%, meeting the standards of pipeline resistance to external pressure and impermeability.
Full aggregate coating: suitable for high-strength pipelines (such as C40-C50 concrete), reducing honeycomb surface, and improving pipeline appearance quality and mechanical properties.
Production efficiency advantages
Fast mixing speed: Compared with traditional forced mixers, the mixing time is shortened by 20%-30% under the same ratio, and the production capacity can be increased by cooperating with automated production lines (such as core mold vibration and suspension roller forming process).
Continuous operation capacity: Wear-resistant lining (such as high manganese steel, polyurethane) and impact-resistant mixing arms are used, which are suitable for industrial mass production, and the average daily mixing volume can reach 100-150 m³.
Process adaptability
Match with pipe forming process:
Core mold vibration process: requires dry hardness of concrete (slump 0-5mm), planetary mixer can provide low air content, high density mixture.
Suspension roller process: requires stable gradation of concrete aggregate, planetary mixing can reduce segregation and ensure uniform thickness of pipe wall.
4.Selection of planetary concrete mixer in concrete pipe production
Single machine capacity: 1.5 m³ mixer has a single mixing cycle of about 2 minutes (including loading, mixing, and unloading), and can produce 40-50 m³ concrete per hour, which is suitable for medium-sized pipe plants (daily production capacity of 50-100 pipes).
Whether online production is required: If docking with an automated production line, it is necessary to confirm that the mixer discharge height matches the conveying equipment (such as belt conveyor, screw conveyor).
5.Concrete pipe type:
Reinforced concrete drainage pipe (RCP): used for municipal drainage, culverts, etc.
Prestressed steel cylinder concrete pipe (PCCP): used for high-pressure water pipelines.
Reinforced concrete pipe (DRCP) for jacking construction: used for trenchless construction.
Supporting equipment: needs to be linked with steel frame forming machine, pipe mold, curing kiln (steam curing or natural curing), etc.
